I'd be inclined to agree. 0.195 (or 0.21 or whatever GM wants to claim now) is too good to have separation there.
However, just today Phil mentioned that he thinks there is separation on the rear glass:
I'd bet against separation though. I wish we had the ear of someone who worked on the project. (FYI we have screen grabs of the EV1 smoke test in the wind tunnel here.)
I would have thought so as well, but the template is supposed to apply in 3D. It's half of a body of rotation. |
I recently purchased a gizmo which converts photographic slides to digital.
I believe I have images of both the EV1 and Ultralite with smoke traces over them in the GM tunnel.
They both have clearly visible separated flow which never re-attaches.I believe they compromised aero for good rearward visibility.
I've also got a side shot of the EV1 at Ft. Stockton setting the LSR with the boat tail.
Roof-to-tail tip angle is 15-degrees instead of about 20.5-degrees.The boat tail angle itself is only 9-degrees
I'll try and get slides scanned for next weekend.
